Certain meat components may increase bladder cancer risk

02.08.2010
A new study suggests that consuming specific compounds in meat related to processing methods may be associated with an increased risk of developing bladder cancer. Published early online in CANCER, a peer-reviewed journal of the American Cancer Society, the findings may be relevant for understanding the role of dietary exposures in cancer risk.

Eating red and processed meats has been linked to an increased risk of developing several different types of cancer. Animal studies have identified a number of compounds in meat that might account for this association. These include heterocyclic amines, polycyclic aromatic hydrocarbons, and N-nitroso compounds. Nitrate and nitrite are added to processed meats and are known precursors to N-nitroso compounds.

Amanda J. Cross, PhD, of the National Cancer Institute in Rockville and colleagues conducted one of the first prospective studies – the NIH-AARP Diet and Health Study—to assess the relationship between intake of these meat-related compounds and the risk of developing bladder cancer. They used information gathered through questionnaires to assess the types of meat consumed as well as how meat was prepared and cooked to estimate the intake of these meat-related compounds.

The investigators had information from approximately 300,000 men and women aged 50 to 71 years from eight US states. At the start of the study (1995 to 1996), all participants completed lifestyle and dietary questionnaires about their usual consumption of foods and drinks. The participants were followed for up to eight years, during which time 854 people were diagnosed with bladder cancer.

People whose diets had the highest amount of total dietary nitrite (from all sources and not just from meat), as well as those whose diets had the highest amount of nitrate plus nitrite from processed meats had a 28 percent to 29 percent increased risk of developing bladder cancer compared with those who consumed the lowest amount of these compounds. This association between nitrate/nitrite consumption and bladder cancer risk may explain why other studies have observed an association between processed meats and increased bladder cancer risk.

"Our findings highlight the importance of studying meat-related compounds to better understand the association between meat and cancer risk," said Dr. Cross. "Comprehensive epidemiologic data on meat-related exposures and bladder cancer are lacking; our findings should be followed up in other prospective studies," she added.

Im Focus: Significantly more productivity in USP lasers

In recent years, lasers with ultrashort pulses (USP) down to the femtosecond range have become established on an industrial scale. They could advance some applications with the much-lauded “cold ablation” – if that meant they would then achieve more throughput. A new generation of process engineering that will address this issue in particular will be discussed at the “4th UKP Workshop – Ultrafast Laser Technology” in April 2017.

Even back in the 1990s, scientists were comparing materials processing with nanosecond, picosecond and femtosesecond pulses. The result was surprising:...

Im Focus: Novel silicon etching technique crafts 3-D gradient refractive index micro-optics

A multi-institutional research collaboration has created a novel approach for fabricating three-dimensional micro-optics through the shape-defined formation of porous silicon (PSi), with broad impacts in integrated optoelectronics, imaging, and photovoltaics.

Working with colleagues at Stanford and The Dow Chemical Company, researchers at the University of Illinois at Urbana-Champaign fabricated 3-D birefringent...

Im Focus: Quantum Particles Form Droplets

In experiments with magnetic atoms conducted at extremely low temperatures, scientists have demonstrated a unique phase of matter: The atoms form a new type of quantum liquid or quantum droplet state. These so called quantum droplets may preserve their form in absence of external confinement because of quantum effects. The joint team of experimental physicists from Innsbruck and theoretical physicists from Hannover report on their findings in the journal Physical Review X.

“Our Quantum droplets are in the gas phase but they still drop like a rock,” explains experimental physicist Francesca Ferlaino when talking about the...

Im Focus: MADMAX: Max Planck Institute for Physics takes up axion research

The Max Planck Institute for Physics (MPP) is opening up a new research field. A workshop from November 21 - 22, 2016 will mark the start of activities for an innovative axion experiment. Axions are still only purely hypothetical particles. Their detection could solve two fundamental problems in particle physics: What dark matter consists of and why it has not yet been possible to directly observe a CP violation for the strong interaction.

The “MADMAX” project is the MPP’s commitment to axion research. Axions are so far only a theoretical prediction and are difficult to detect: on the one hand,...
